转移树

本方法原理上推广了Viterbi译码算法，形成一个需要兼顾信道编码序列流的最优路径与多路信源编码状态转移树中的最大先验概率的译码算法。

Our method generalize the conventional Viterbi decoding algorithm , not only the optimal path in channel decoding trellis but also the a priori probability of branches in multiple VLC source trees are considered .

近20年来，朱鹮的营巢地逐渐由海拔1200m左右的中山地区向海拔800m左右的低山丘陵地区转移，巢树树种由栓皮株变为以马尾松为主。

In the recent 20 years , the average elevation of nest sites of the Crested Ibis changed from about 1200m in middle mountain area to about 800 m in hill area , the main nest species changed from Oak to Masson Pine .

重点在于用产生式和框架式进行知识的表示，以及状态空间转移法和故障树深度优先查询法的研究和实现。

Key lies in the knowledge denotation through the method of production pattern and the frame posture , As well as the method of state-space transfer and the depth first inquiry of fault tree were researched and realized .

在实现了定性分析和定量计算等基本功能的同时，采用模块化和转移事件的故障树简化技术，实现了对复杂故障树的分析计算。

The thesis completes the basic function such as qualitative-analysis and quantified-analysis , at the same time , it applies a technique based on modules and transfer events to simplify fault tree , and achieve the analyses and calculate of big fault tree .
